Print head, manufacturing method therefor, and printer

Abstract

A print head is provided with at least ink-pressurizing cells, heating elements, and ink-ejection nozzles. In addition, the print head includes substrate members which form side surfaces and one end surface of the ink-pressurizing cells, and which are provided with the heating elements; a nozzle-formed member which forms the other end surface of the ink-pressurizing cells, and in which the ink-ejection nozzles, which individually correspond to the ink-pressurizing cells, are formed; and a head frame which supports the nozzle-formed member.

1. A print head having ink-pressurizing cells, heating elements, and ink-ejection nozzles, the print head comprising:
 a substrate member which forms side surfaces and one end surface of the ink-pressurizing cells and which is provided with the heating elements;  
 a nozzle-formed member which forms the other end surface of the ink-pressurizing cells, and in which the ink-ejection nozzles, which individually correspond to the ink-pressurizing cells, are formed;  
 a head frame which supports the nozzle-formed member; and  
 a plurality of substrate units, each of which includes a plurality of substrate members, are provided for individually ejecting inks of different colors, and wherein the substrate members included in the substrate units are attached to a single nozzle-formed member.  
 
     
     
       2. A print head according to  claim 1 , wherein a plurality of substrate units, each of which includes one or more substrate members, are provided for individually ejecting inks of different colors, and wherein the substrate members included in the substrate units are attached to a single nozzle-formed member. 
     
     
       3. A print head according to  claim 1 , wherein the print head is a line head. 
     
     
       4. A print head according to  claim 1 , wherein the nozzle-formed member is formed of a material comprising nickel.
